US Banknotes

The seal color is actually considered to be yellow rather than gold. All yellow-seal $1 silver certificates were dated 1935 A.

As of 12/2011, these bills sell for $10 to $20 in circulated condition. A nice uncirculated one can bring $200 or more.

During WWII special bills were printed for use in threatened or combat areas. They had distinctive ink colors (yellow for North Africa and brown for Hawaii) so they could be easily recognized and declared worthless if they fell into enemy hands.

No one's picture is on a US million dollar bill because that denomination doesn't exist. Any "million dollar" bills you may see are well-known novelty items that sell for a few bucks online and in gift shops.

The largest bill printed for circulation was worth $10,000, and the largest bills ever printed were a set of special $100,000 gold certificates made for internal bank transfers.

US $2 bills are printed by the Bureau of Engraving and Printing, the same agency that prints all US currency.

Contrary to popular myth, $2 bills aren't rare, haven't been discontinued, and are still being produced. They only make up about 1% of all paper money in circulation but that still amounts to hundreds of millions of bills.

Please check the date again and post a new, separate question. The US didn't print any bills of any denomination dated 1930.

Yes

It's still worth $50.

It's a blend of 75% cotton and 25% linen with red and blue fibers mixed in.

No, although the components are similar. The "paper" used for US currency is made from a special fiber blend consisting of roughly 3/4 cotton and 1/4 linen.

Generally about $1000, but this depends on a few factors.

Could be worth something, depending on its condition and variety (signature combinations, variants, etc).

It depends on its date, series letter, and condition. A 1957, 57-A, or 57-B bill is so common that you'd be lucky to get more than 25¢ or 50¢ extra if you sold it to a dealer.

An older bill might bring more but again it depends on those same factors. If the extra value is significant and you have an eBay account or something similar, you might be able to get close to its retail value by selling it online.

"G" is the Federal Reserve District letter rather than the series letter; if there is one it's next to the date.

The fact that your bill is a Federal Reserve Note means it was printed in 1976 or later and is not rare. If you got it in change it's only worth face value.

"F" is the highest series letter for 1928 $5 red-seal notes. Please check your bill again and see the question "What is the value of a 1928 US 5 dollar bill with a red seal?" for more information.

The US didn't print any bills dated 1930. Please check again and post a new, separate question.

The Bureau of Engraving and Printing makes uncut sheets available to collectors. However there's not a very large market for them. It's not a scam but it's also not likely anyone will get rich buying them.

Yes, but it wouldn't make much sense because the bill is probably worth more to a collector depending on its condition.

The US never withdrew or demonetized any older currency except for gold certificates, so a 1934-series bill is still legal tender along with other old Federal Reserve Notes, silver certificates, United States Notes, and so on.

1928 A and 1928 B are the only small-size $2 bills that carry a significant premium. Circulated bills with an "A" series letter might bring $50 to $80 at retail depending on their condition, while "B" bills retail for $70 to $175.

By contrast, nearly all pre-1928, large-size $2 bills sell for significant premiums. Values range from $50-$75 for a 1917 $2 US Note up to $550-$2500 for an 1890 Treasury Note. Uncirculated specimens can be worth even more.

The US dollar bill with the highest circulation today is the $100.

Other bills with a higher amount are currently not in circulation. These include $500, $1000, $5000, and $10,000. While technically still legal to use, they're worth more to collectors.

There were also special $100,000 bills printed for use inside the government but these were never available to the general public.

Redemption of silver certificates for silver metal was stopped back in 1968. Since then they've been treated like any other paper currency.

Depending on your bill's date and condition it may be worth anywhere from just face value to a lot more. Please post a new, separate question with its date and what letter if any is next to the date.

$100 has been the largest denomination printed since 1945. Those and all smaller denominations - $1, $2, $5, $10, $20, and $50 - remain in regular production.

Prior to 1945 the US also issued $500, $1000, $5000, and $10,000 bills for general circulation as well as special $100,000 bills that were only used by the Federal Reserve System. Printing of high-denomination bills was suspended in 1945 because of low use. Due to concerns about the bills being used by organized crime that suspension was made permanent in 1969. Banks are no longer allowed to distribute the bills and are required to hold any that are received.

The old bills were never recalled or demonetized so they're technically still legal to spend, but they're worth more than face value to collectors and dealers.

Not rare. Is worth only $1.50 in circulated condition and $7+ in uncirculated condition.

US bills have a significant number of security features. New higher-denomination notes ($5 and above) have more features than old-style $1 and $2 bills. You can read about them at the Bureau of Engraving and Printing website, linked below:

To clear things up, the bill wasn't printed in Philadelphia. That's the Federal Reserve District that distributed the bill, but it was printed in Washington.
